Peter Jackson has confirmed that a new trailer for his hyped first Hobbit film will be released on Wednesday.

In a video posted on Facebook, Jackson gave few details away about the new trailer for The Hobbit: An Unexpected Journey, due for release on December 14.

It's the second trailer to be released for the film, and Jackson said it was timed to coincide with Tolkien Week - the 75th anniversary of the release of JRR Tolkein's The Hobbit.

"Our contribution to the celebrations is going to be debut our new trailer for The Hobbit on the 19th ... we're also going to share some special content with you, the fans. So check back with us in a day or two," Jackson said.
